The sequence of the first five N-terminal amino acids was determined and was found to be Met-Leu-Lys-Thr-Leu.
The Biological Activity was determined by measuring the dose dependent activation of STAT3 in human epidermal keratinocytes (HEKa cells).Significant STAT3 activation is observed with 100 ng/mL of recombinant human IL-20 corresponding to a Specific Activity of 10,000IU/mg.
Lyophilized carrier free.
Sterile Filtered White lyophilized (freeze-dried) powder.
Greater than 95.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.
It is recommended to reconstitute the lyophilized Interleukin -20 in sterile 18MΩ-cm H2O at a concentration of 0.5mg/ml or less.
Lyophilized Interleukin-20 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution IL20 should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please avoid multiple freeze-thaw cycles.
IL10D, ZCYTO10, IL-20, MGC96907, Four alpha helix cytokine Zcyto10.
